Is Iran Mass Producing Advanced Gas Centrifuge Components? Can we even know with the way the Iran deal has been structured and implemented so far?

The head of Iran’s nuclear program says Iran has the capability to initiate mass production of advanced centrifuges on short notice. The mass production of these centrifuges (or their components) would greatly expand Iran’s ability to sneak-out or breakout to nuclear weapons capability or surge the size of its centrifuge program if the deal fails or after key nuclear limitations end. If Salehi’s statement is true, Iran could have already stockpiled many advanced centrifuge components, associated raw materials, and the equipment necessary to operate a large number of advanced centrifuges. The United States and the International Atomic Energy Agency (IAEA) need to determine the status of Iran’s centrifuge manufacturing capabilities, including the number of key centrifuge parts Iran has made and the amount of centrifuge equipment it has procured. They need to ensure that Iran’s centrifuge manufacturing is consistent with the intent of the nuclear deal as well as the deal’s specific limitations on advanced centrifuges. Moreover, the Iranian statement illuminates significant weaknesses in the Iran deal that need to be fixed.
